Descripción
This SKF cylindrical roller bearing with a polyamide/nylon cage and removable outer ring is suitable for applications that support high radial loads. This roller bearing has a CN (normal) radial clearance for applications and operating conditions with normal shaft and housing tolerances where thermal expansion is not a factor. This is a double row roller bearing that supports higher radial loads than single row bearings. A removable outer ring in the open bearing allows application of lubrication. The polyamide/nylon cage prevents the rollers from coming into contact with each other during use to reduce friction, vibration, and noise and weighs less and is quieter than cages made of brass. Cylindrical roller bearings are used in applications where high radial loads are present such as in conveyer belts, traction motors, railway car axle boxes, and oilfield mud pumps, among others.Roller or rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. They are usually composed of two rings, rolling bodies (such as bearings or cylinders), and a cage to house the parts. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Rolling bearings can be open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.SKF manufactures bearings, seals, and lubrication systems for automotive, OEM, energy, and other and industrial applications. The company, founded in 1907, is headquartered in Gothenburg, Sweden, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
